Abstract
The present invention provides a liquid spray gun with several improved features, including (1) a molded polymeric possibly disposable body assembly through which passes liquid sprayed by the spray gun that is manually releasable from a metal platform portion of the spray gun through which air is fed to passageways through the body assembly to spray the liquid; (2) non-cylindrical air passageways on air horns that provide improved shape and uniformity for the wide elongate stream of liquid formed by the spray gun, and (3) an air cap portion of the body assembly mounted for manual rotation on a nozzle portion of the body assembly between positions defined by stops and retained at those positions by friction.
